Abstract

PURPOSE:To ensure holding of a tape and to prevent displacement of a tape even during high speed rotation by forming a notch in a tape by means of the mounting blade of a drum for a notch blade, stopping a roller for mounting a tape, and cutting the tape in a state to exert a tensile force on the tape. CONSTITUTION:A substance to be mounted fed from the direction of an arrow mark A is guided by a guide member 20 and conveyed by a conveyance belt 13 and a carry-in roller 16. Meanwhile, a tape 18 is delivered to a roller 5 for mounting a tape, and a notch is formed in the tape 18 by means of a drum 6 for a notch blade. When the substance to be mounted is moved to a mounting position, a roller 5 is rotated by means of an electromagnetic clutch brake 35 to deliver the tape 18. The tip thereof is placed on the substance to be mounted, and the tape 18 is delivered over the substance to be mounted in synchronism with a moving speed. When the substance to be mounted is moved in a state to be nipped between the belt 13 and the roller 5, the tape 18 is mounted on the substance to be mounted. When rotation of the roller 5 is stopped by means of a brake 35, a tensile force is exerted on the tape 18 since the substance to be mounted is under movement, and the tape 18 is cut from a notch part.

Description

DETAILED DESCRIPTION OF THE INVENTION (Field of Industrial Application) The present invention relates to a tape pasting device for pasting double-sided tape onto envelopes, posters, etc., for example.

(Prior Art) As shown in FIG. 12, a tape 2 is continuously attached to an envelope l. Further, as shown in FIG. 13, tape 4 is intermittently pasted on large items such as posters.

In this way, the tape applicator is required to have both continuous and intermittent tape applicability functions.

Conventional tape pasting devices include, for example, the Japanese Patent Publication No. 35-264
As disclosed in Publication No. 9, there is a tape pull-out roller that is rotated by an electric latch that stops after each rotation, and the tape pulled out by this pull-out roller is vacuum-adsorbed and the tape is applied to an object. It mainly consists of a pasting roller that pastes the paste, and a knife that is extended and retracted by a solenoid. In this conventional tape applicator, the tape pulled out by the pull-out roller is vacuum-adsorbed and conveyed to the continuously rotating applicator roller, and in the process, it is adsorbed to the applicator roller by a knife protruded by a solenoid. The tape is cut. Then, when the pull-out roller rotates once and stops using the clutch, the tape is intermittently attracted to the outer circumferential surface of the applicator roller while being separated from the part cut by the knife. It is pressed against the object and is intermittently affixed to the object. When changing the length of the tape, the pull-out roller and application roller are replaced with diameters that match the length of the tape.

Another conventional example disclosed in Japanese Utility Model Application Publication No. 60-78355 sets the tape application start position, tape application length, and length of the non-applied part of the tape in the case of intermittent application as a counter. The number of rotations of the slit plate attached to the conveyance roller or the tape feeding roller of the object to be pasted is counted by a pulse count detection device, and the count is read by comparing it with the set values of the respective counters set above. Then, based on this count signal, the feed roller and cutter solenoids are operated to feed and cut the tape a predetermined length, thereby supplying a predetermined length of tape and attaching the tape to the object.

(Problem to be Solved by the Invention) In the above conventional example, the one disclosed in Japanese Patent Publication No. 35-2649 is that when the tape is applied intermittently or continuously, the length of the tape is Since it is necessary to replace the pull-out roller and pasting roller with a diameter that matches the diameter of the roller, there is a problem that the replacement is time-consuming and reduces work efficiency.

Further, in the case of the method disclosed in Japanese Utility Model Application Publication No. 60-78355, although it is possible to perform intermittent pasting, it is not possible to perform continuous pasting.

In other words, in this tape application device, the tape application start position, the tape application length, and the length of the non-applied part of the tape in the case of intermittent application are set in the counter, and the tape The number of rotations of the slit plate attached to the feed roller is counted by a pulse count detection device, and the count is read by comparing it with the set value of each counter set above. Based on this count signal, the number of rotations for the feed roller and cutter is Since the solenoid is operated to feed and cut the tape a predetermined length, the tape is always cut by the cutter.

For example, if you set the length of the non-applied part of the tape to zero when applying it intermittently, the tape will be applied as if it were continuous without any gaps at the cut part of the tape, but if the upper paper of the double-sided tape is Since the top paper is cut short when it is peeled off, there is a problem in that the top paper must be peeled off many times.

In addition, if the tape application length is set to the length required for continuous application, the distance between the feed roller that sends out the tape and the cutter may be increased, or the distance may be made variable. Therefore, there are problems in that the tape applicator becomes large and has a complicated structure.

Next, in all of the above-mentioned conventional examples, the tape is cut before being attached to the object, so there are the following problems.

In other words, since the cut tape is only vacuum-adsorbed to the outer circumference of the application drum, if the surface of the object to be applied does not hit the adhesive surface of the tape on average at the moment of starting application, the outer circumference of the application drum The tape, which is vacuum-adsorbed to the surface, becomes misaligned on the outer circumferential surface of the application drum.

Therefore, in the case of continuous pasting, the pasting may be bent, and in the case of intermittent pasting, the pasting may become disordered, resulting in poor pasting. In addition, when the application drum is rotated at high speed to increase the application efficiency, the force with which the tape adhesive surface of the object to be applied collides with the object at the moment of starting application increases, so that the tape is even more disturbed on the outer circumferential surface of the application drum. There is a problem that this increases the size, further increasing the possibility of poor adhesion.

Furthermore, in order to reduce the disturbance of the tape on the outer peripheral surface of the application drum, a guide roller must be provided opposite the application drum in order to improve the biting of the object to be applied at the beginning of application. Therefore, there is a problem that the structure becomes complicated.

The present invention provides a tape pasting and applying device which has a simple structure, has continuous pasting and intermittent pasting functions, and solves the conventional problems by cutting the tape while pasting the tape to the object to be pasted. It is.

(Means for Solving the Problems) The means according to the present invention for solving the above problems is such that a tape applying roller is provided so that its outer periphery faces the transport surface of a horizontally installed transport conveyor. A drum for notch blades is provided on the side of the roller for applying tape that brings in the object to be pasted, and a roller for pulling out a tape and a roller for guiding tape are arranged above the roller for applying tape, and the blades are mounted on the drum for notch blades. A notch is made in the tape, the rotation of the tape application roller is stopped, and a tensile force is applied to the tape to cut the notch.

The second invention provides a tape applying roller so that its outer periphery faces the conveying surface of a horizontally provided conveyor,
A drum for a notch blade is provided on the side of the tape applying roller in which the object to be pasted is brought in, and a tape pull-out roller and a tape guiding roller are provided above the tape applying roller, and A tape sticking roller drive gear, a notched blade drum gear,
A pull-out roller gear and a guide port to lugia are provided, and the tape application roller drive gear and notch blade drum gear are connected via an electromagnetic clutch, and the tape application roller is connected via an intermediate gear that meshes with the tape application roller drive gear. The rotation of the drive gear is transmitted from the pull-out roller gear to the guide roller gear, and the driving force of the drive source is transmitted via the electromagnetic clutch brake to the tape application roller drive gear, and also via the conveyor belt intermediate gear. It is characterized by transmitting the power to the gear.

A third aspect of the invention is that, in the above-mentioned tape applicator, a sensor for detecting the object to be applied is provided on the inlet side of the notch blade drum, and a switch for switching between intermittent and continuous application of the tape, and a switch for changing the application length and application interval of the tape are provided. A tape application instruction switch is provided, an encoder gear is provided coaxially with the intermediate gear for the conveyor belt, and signals from the changeover switch and the tape application instruction switch are calculated;
The tape is characterized in that the position of the object to be applied is detected by a sensor and an encoder, and the electromagnetic clutch brake and the electromagnetic clutch are controlled, and the tape is applied continuously or intermittently to the object to be applied.

(Function) Since the present invention is configured in this way, the tape fed to the tape application roller via the tape pull-out roller and tape guide roller provided above the tape application roller is transferred to the notch roller. A cut is made by the provided notch blade. Then, a tape sticking roller drive gear, a notch blade drum gear, a drawer roller gear, and a guide roller gear are provided on the respective shafts of the notch blade roller, tape pull-out roller, and tape guide roller,
The tape application roller drive gear and the notch blade drum gear are connected via an electromagnetic clutch, and the rotation of the tape application roller drive gear is transferred from the drawer roller gear to the guide roller gear via an intermediate gear that meshes with the tape application roller drive gear. The driving force of the drive source is transmitted to the tape applying roller drive gear via the electromagnetic clutch brake and to the conveyor belt gear via the intermediate gear for the conveyor belt, and the driving force is transmitted to the conveyor belt gear via the conveyor belt intermediate gear. By controlling the electromagnetic clutch and brake, the tape is cut while being attached to the object by being pulled through the cuts made by the notch blade. and,
By controlling the electromagnetic clutch and the electromagnetic clutch brake, the tape can be applied continuously or intermittently.

A third invention is one in which a means for controlling the electromagnetic clutch and the electromagnetic clutch brake is added so that the tape can be applied continuously or intermittently. It is detected by a sensor installed on the side. Then, intermittent pasting and continuous pasting of the tape is selected by a changeover switch. The length and interval of tape application are set in advance by a tape application instruction switch.

The position of the object to be pasted is determined by detecting the distance traveled by the object from the time the object passes the sensor using an encoder attached to an intermediate gear for the conveyor belt with an encoder gear provided coaxially therewith. That is, an instruction signal indicating whether to apply the tape intermittently or continuously selected by the changeover switch and a signal indicating the tape application length and application interval from the tape application instruction switch are calculated, and the moving distance of the object to be applied is calculated using a sensor and an encoder. Detects and controls electromagnetic clutch brake and electromagnetic clutch. As a result, the rotation of the notch blade drum is controlled via the electromagnetic clutch brake, and while notching the tape to a predetermined length, the tape application roller rotates via the electromagnetic clutch to feed out the tape. It is controlled to stop, apply the tape to the object, apply tension to the tape, and cut the tape from the cut line.

It is designed to allow access to the entire surface of the tape, and is designed to guide the tape so that it does not sag when attached to large items such as posters. An anti-slip member 28 is provided on the inner surface of the tape reel 19, and serves as a brake to prevent the tape 18 from loosening due to its inertial force when it is pasted intermittently.

In FIG. 3, the conveyor belt 13 is an endless belt that is passed around a sprocket 29, and a part of the pasting table 12 is cut out so that the conveying belt 13 is exposed on the upper surface of the pasting table 12. A plate spring 30 is provided between the carry-in rollers 16 and loosely contacting the conveying surface of the conveying belt 13 with elastic force to prevent the object to be pasted from folding. A guide bar 31 is provided close to the outer periphery of the tape applying roller 5 and as close to the conveyor belt 13 as possible, and guides the cut end 32 of the tape 18 so as to approach the conveyance surface of the conveyor belt 13. . 261
6 is the insertion hole of the guide bar 26 shown in FIG.
is transmitted to the pulley 35 of the electromagnetic clutch brake.

In FIG. 1, the tape applying roller 5 has a tape applying roller drive gear 501, the notch blade drum 6 has a notch blade drum gear 601, the tape pulling roller 7 has a tape drawing roller gear 701, and the tape drawing roller 7 has a tape drawing roller gear 701. Guide roller gears 801 are provided coaxially with each guide roller 8,
Further, a conveyor belt intermediate gear 9 and an encoder gear 38 are coaxially provided on the pulley 34, and a conveyor belt gear 10 is provided on the sprocket 29, respectively. The encoder 39 is rotated by meshing with the encoder gear 38. The tape application roller drive gear 501 and the notch blade drum gear 601 are engaged with each other via an electromagnetic clutch.

Power transmission is performed as follows. The power output from the pulley 33 attached to the power source is transmitted through the belt 36.
．． It is simultaneously transmitted to the pulley 34 and the pulley 35 of the electromagnetic clutch brake via the pulley 37. The power output to the pulley 34 is output to the conveyor belt gear l port via the conveyor belt intermediate gear 9 to drive the conveyor belt 13 and also drives the encoder 39 via the encoder gear 38. On the other hand, the power output to the pulley 35 is output to the pulley 41 via the belt 42, and the tape application roller drive gear 501 is rotated via the belt 43.
The rotation of the tape sticking roller drive gear 501 rotates the notched blade drum gear 601 which meshes with the tape sticking roller drive gear 501 and the intermediate gear 40, and the drawer roller gear 701 and the drawer roller gear 70 which mesh with the intermediate gear 40.
1 and is transmitted to the guide roller gear 801 that meshes with the guide roller gear 801.

Therefore, the tape application roller drive gear 501 is rotated via the electromagnetic clutch brake (pulley 35), and the notched blade drum gear 601 is rotated by the tape application roller drive gear 501 via the electromagnetic clutch. . In addition, the drum gear 601 for notchi blades
, intermediate gear 40. The pull-out roller gear 701 and the guide roller gear 801 are all connected to the tape application roller drive gear 5.
Since the tape application roller drive gear 501 is rotated by 01, all of these gears also stop when the tape application roller drive gear 501 stops. And a tape application roller drive gear 50
1. Notch blade drum gear 601, drawer roller gear 7
0I, guide roller gear August are respectively tape pasting roller 5, notch blade drum 6, tape pulling roller 7,
Since it is coaxial with the tape guiding roller 8, the tape applying roller 5, notch blade drum 6, tape drawing roller 7, and tape guiding roller 8 also rotate in synchronization with their respective gears. Further, the tape sticking roller drive gear 501, notch blade drum gear 601, drawer roller gear 701, and guide roller gear 801 are respectively replaced by the tape sticking roller 5, the notch blade drum 6, the tape drawing roller 7, and the tape guiding roller 8. , to form a group of gears and attach them to one board, and swing this group of gears about the axis of the pulley 41 as a fulcrum. The outer peripheral surface of 5 is pressed with an appropriate pressing force.

The operation of this embodiment configured in this way will be described next. The object to be applied is supplied from the direction of arrow A (Fig. 4).
It is guided by the guide member 2a and transported by the transport belt I3 and the carry-in roller 16. On the other hand, the tape 18 is fed out by the rotation of the tape sticking roller 5, and the notch blade drum 6 is rotated by the electromagnetic clutch to put a notch in the fed tape 18. Then, the rotation of the tape application roller 5 is controlled to stop by the electromagnetic clutch brake 35, and the tape application roller 5 is on standby. Next, when the object to be pasted reaches the pasting position, the tape pasting roller 5 is rotated by the electromagnetic clutch brake 35, the tape 18 is fed out, the tip of which is placed on the starting position of the pasting object, and the object is moved. The tape 18 is fed out onto the surface of the object in synchronization with the speed. In this state, the object to be pasted is on the conveyor belt 13.
As the tape 18 placed on the surface of the object is pressed against the surface of the object, the tape 18 is affixed to the object. . Next, when the rotation of the tape application roller 5 is stopped by the electromagnetic clutch brake 35, the object to be applied is continuously moved by the continuously driven conveyor belt 13, so the tape 1
A tensile force is applied to the tape 18, and the tape 18 is cut from the notch. In this way, from the moment the tape is applied to the object until it is cut, the tape is guided by the tape application roller 5, tape pull-out roller 7, and tape guide roller 8 without being cut. The tape is held on the outer periphery of the tape applying roller 5 without shifting. Further, when the tape 18 is cut, a tensile force is applied to the tape 18, so that the tape 18 is held stably.

In this way, the tape 18 is applied to the object to be applied, but when applying it continuously or intermittently, the tape 18
8 is determined by turning the electromagnetic clutch on and off in accordance with the timing of the tape 18 being sent out by the tape pasting roller 5, operating the notch blade △ drum 6, and putting a notch in the tape I8.
The length of the tape is adjusted to any length suitable for continuous pasting and intermittent pasting, and when cutting the tape 18, the electromagnetic clutch brake 35 is turned on and off to stop the rotation of the tape pasting roller 5. Do it under control.

Next, another embodiment will be described using FIG. 2. This is done automatically. Therefore, explanations of parts that overlap with those in FIG. 1 will be omitted here. In FIG. 13, when pasting intermittently on the object 3, the dimensions of the pasting start position a, tape length b, interval ci5, and pasting end d are set by the digital switch 22 (tape pasting instruction switch). Ru. 48 has a small set value extraction section. Further, selection between continuous pasting and intermittent pasting is made with the changeover switch 23. 49 is located above the selection value extraction section. The signals from the setting value extracting section 48 and the selected value extracting section 49 are input to the @ calculation section 46. The control unit 47 includes the calculation unit 46, the sensor 25, and the output unit 5 of the encoder 39.
1 controls the electromagnetic clutch brake 44 and the electromagnetic clutch 45.

Next, the operation of this embodiment configured as described above will be explained using FIG. 2, FIG. 6, and FIG. 11.

(1) First, to explain intermittent pasting, the switch 52
to turn on the brake of the electromagnetic clutch brake 44 and the motor M. Next, the changeover switch 23 is used to switch to the intermittent pasting side, and the digital switch 22 is used to set the pasting start position a, tape length b, interval C, and pasting end d. Then, this set value and the signal from the changeover switch 23 are manually input to the calculation unit 46, and if the condition is met, the sensor 25 is turned on, and if not, the setting is redone (step Sl).
. When the conditions are satisfied in this way, the calculation section 46 outputs the signal to the control section 47, and the control is performed as follows.

In FIG. 2 and FIG. 5, A is the position where the tape is notched, B is the tape stop position, and C is the position where the tape is applied by pressing the object between the tape application roller 5 and the conveyor belt 13. D is the position where the tape is pasted on the object, D is the position where the sensor 25 detects the object, E is the position where the notch blade 53 makes a notch in the tape, F is the stop position of the notch blade 53, and G is the position of the tape pasting roller 5. This is the relative attachment start position where the tip of the tape is located at position B. When the position of each process is defined like this.

The tape length is regulated between AB, and the relative pasting position G is between BC.
The tip of the tape is placed on the predetermined position of the object to be applied, and the tape is fed out relative to the moving speed of the object by the rotation of the tape application roller 5 and is placed on the surface of the object to be applied. This is the section where the tape is temporarily placed, the distance between CD is the absolute pasting distance of the object to be pasted, and the distance between EF is a notch for putting a notch at the set length position of the tape sent out by the rotation of the tape pasting roller 5. This is the section in which the blade drum 6 rotates. In this section, the output pulses of the encoder are counted to detect the relative position of the tape application roller 5 and the notch blade drum 6 relative to the amount of movement of the object.

In the control section 47, based on the signal from the calculation section 46, the signal from the sensor 25, and the signal from the encoder 39,
After calculating the CD-BC and outputting the set value of the pasting start position (step S2), the clutch of the electromagnetic clutch brake 44 is turned on to rotate the tape pasting roller 5 (between BC). When the rotation of the tape application roller 5 reaches the set tape length (between EF), an output is sent to the electromagnetic clutch 45 (
Step S3) Rotate the notch blade drum 6 to make a notch in the tape.

Thereafter, the notch blade drum 6 rotates for a predetermined period of time using a timer, and the electromagnetic clutch 45 is set to F.
rotation stops. This causes the notch blade drum 6 to stand by in the next operating state. Next, when the tape application roller 5 reaches the stop position (B) (step S
4) The clutch of the electromagnetic clutch brake 44 is turned off and the rotation of the tape application roller 5 is stopped. This applies a tensile force to the tape, and the tape is cut from the notch. Next, in step S5, the tape applying roller 5 opens and stops the portion where no tape is applied (C in FIG. 13), and then the process returns to step S2 to repeat the control.

In this intermittent pasting, in step S3 (Fig. 7), if the tape pasting length EF is less than the set value, a NO signal is output and the sensor 25 does not turn OFF (step StO in Fig. 8). The tape 201 is stopped to prevent the tape 201 from sticking out from the object 3 as shown in Fig. 13 e.
5 is turned off, the final length of pasting is confirmed by the pulse counter after the sensor is turned off (step Sll).
Similarly, the tape is prevented from sticking out from the object 3 to be pasted. When the final length of pasting satisfies the set value, the electromagnetic clutch 45 is turned on and after making a notch in the tape 18, the notch blade drum 6 is rotated for a predetermined time by a timer, and the electromagnetic clutch 44 is turned on after a predetermined time. OFF
Then, the notch blade drum 6 stops rotating and waits for the next operation. Next, when the tape application roller 5 reaches the stop position (B) (step S12), the clutch of the electromagnetic clutch brake 44 is turned off (FIG. 9), and the rotation of the tape application roller 5 is stopped. As a result, a tensile force is applied to the tape 18, and the tape 18 is cut from the notch portion.

(2) Next, continuous pasting will be explained. When the changeover switch 23 is switched to continuous pasting, the sensor 25 is turned on (step S6). Next, the controller 47 calculates GO-BC (FIG. 10), outputs the set value for the starting position of pasting (step S7), turns on the clutch of the electromagnetic clutch brake 44, and turns on the tape pasting roller 5. Rotation (between BC)
At the same time, sensor 25 is turned off, and sensor 25
After turning OFF, the pulse counter outputs the set value at the end of pasting.S8) Turn on the electromagnetic clutch 45, rotate the notch blade drum 6, and put a notch in the tape 18. After the notch blade drum 6 rotates for a predetermined period of time, the electromagnetic clutch 45 is turned off, and the notch blade drum 6 stops rotating and waits for the next operating state. Next, when the tape application roller 5 reaches the stop position (B), the clutch of the electromagnetic clutch brake 44 is turned off to stop the rotation of the tape application roller 5 (step 591).As a result, a tensile force is applied to the tape 18, and the tape 18 is cut from the notch portion.Then, the process returns to step S6 and the continuous pasting is repeated.

(Effects of the Invention) As detailed above, according to the present invention, the conveyor belt and the tape application roller are driven by one drive source,
The tape application roller is driven via an electromagnetic clutch brake, and the notch blade drum is driven by the tape application roller via an electromagnetic clutch, making it easy to insert the notch at a predetermined length of tape. The tape can be cut while applying tensile force to the tape.

This ensures that the tape is held securely, and the tape will not shift even when rotated at high speed.

In addition, by making a notch in the tape so that the tape does not have to be cut before being applied to the object, the length of the tape can be adjusted as desired by adjusting the amount of feed.
Moreover, since the guide roller is not required and the power is transmitted by a group of gears provided on the same axis, it is possible to further reduce the size.

In addition, a sensor that detects the relative position of the object to be pasted, a switch to switch between intermittent tape application and continuous tape application, and a tape application instruction switch that indicates the tape application length and interval are installed, and the intermediate gear for the conveyor belt is coaxial. An encoder is provided via an encoder gear provided in the encoder, and the signals from the changeover switch and the tape application instruction switch are calculated;
Since the sensor and encoder detect the position of the object to be pasted and control the electromagnetic clutch brake and electromagnetic clutch, a notch is placed in the tape, a tensile force is applied to the tape, the tape is cut from the notch, and continuous pasting is possible. And intermittent pasting can be performed automatically.

This enables high-speed application and greatly improves tape application efficiency.
